ManagedProcess 实现 ProcessInfo，Launcher#launch、ProcessListener 及启动事件改用 ProcessInfo，GameCrashWindow、LogWindow、LauncherHelper、HMCLGameLauncher 随之适配；并从 UpdateHandler 提取 JavaProcessLauncher 至 HMCLCore。

额，能问一下下面这张图为什么多了一个将近 800MB 内存的后台 java 进程吗？

这个是构建项目的进程，gradlew run 就会有。你可以看下，两张图都有一个 ~800M 的 java 进程。至于为什么一会后台一会前台我就不是很清楚了 |

当前特性需设置
HMCL_USE_HMCLMONITOR环境变量启用效果
不设置
HMCL_USE_HMCLMONITOR：HMCL 常驻占用 ~400MB
设置
HMCL_USE_HMCLMONITOR：HMCL 常驻占用 ~45MB
启动器可见性：隐藏启动器并在游戏启动后重新打开
显示日志：关
系统：Windows 11 25H2
本机测试 HMCL 内存占用降低 ~85%
新增内容
新 Gradle 子项目
HMCLMonitor依赖
HMCLCore，与HMCLBoot以同样方式打包进 HMCL 主 jar。主项目启动游戏时，将启动参数写入 specFile，同时启动一个带参数的 HMCL 进程，主进程按照可见性退出。
使用
--monitor <specFile>参数启动 HMCL 以使用 HMCLMonitor。此模式下，不初始化 HMCL 的大部分功能，并能：specFile 见 ProcessSpec.java
新 HMCL 启动模式
使用
--crash-report <resultFile>读取HMCLMonitor生成的游戏进程报告，并在启动后弹出一个崩溃窗口。resultFile 见 ResultSpec.java
修改内容
HMCLCore: 重构游戏进程视图
新增
ProcessInfo接口，统一 “本 JVM 直接持有的游戏进程” (ManagedProcess) 与 “monitor 代管的游戏进程” (MonitorGameProcess) 的视图，相关 API 签名从ManagedProcess改为ProcessInfo。HMCLCore: 提取实用方法
将
UpdateHandler中 “复用当前 JVM 参数拉起新 java 进程” 的逻辑提取为JavaProcessLauncher，由UpdateHandler与 monitor 共用。
